A bug fix just introduced incorrect behavior in the omap2 nand driver, as
found by gcc-6.1:

drivers/mtd/nand/omap2.c: In function 'omap_get_dt_info':
drivers/mtd/nand/omap2.c:1658:2: error: this 'if' clause does not guard... [-Werror=misleading-indentation]
  if (!info->elm_of_node)
  ^~
drivers/mtd/nand/omap2.c:1660:3: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'if'
   if (!info->elm_of_node)
   ^~

We clearly need to put the indented code into { } braces to get the intended
behavior.
